Question juridique clé
Whether the subsidiary constitutional complaint and civil appeal were admissible against the cantonal decisions
Solution extraite
The subsidiary constitutional complaint was inadmissible, and the civil appeal could not be used to obtain review of the unreviewable constitutional complaints or the non-final commercial court decision on foreign law.
Motifs extraits
The appellants raised only constitutional grievances and did not properly challenge the cassation court's reasoning. Where the Federal Court's review power was no broader than the cassation court's, the commercial court decision could not be directly attacked under Art. 100 Abs. 6 BGG; moreover, the complaints lacked proper substantiation.
